Get your whole house fan and beat the heat!

All this cool evening air. Ready to use.

AirScape your home.
It’s the smart green alternative to A/C.

Whenever evenings cool off, it just makes sense to harness the cool fresh air nature provides, rather than expensively conditioning your own. An AirScape whole house fan creates a wonderfully fresh living and sleeping environment, for a fraction of the cost of A/C. It's one of the best energy efficiency investments you can make, and one of the most enjoyable too.

How it works

As soon as the evening cools off, your AirScape can come on. It's designed to quietly run all night, steadily drawing cool fresh air in through open windows while exhausting hot stale air out through attic vents. This creates a cool, fresh, natural living and sleeping environment while drawing heat out of the structure to reduce A/C load for the next day.


It lives in your attic

Powerful, yet ultra-quiet and efficient. The AirScape Sierra & Ventura deliver stealthy whole house ventilation, pushing hot air out through existing attic vents, and drawing cool evening air in through open windows.

Energy Savings Estimator

Depending on where you live, your home’s construction and your A/C habits, an AirScape whole house fan can reduce your cooling costs up to 50-90%.

The secret to the best fans in the business

Unlike our competitors, we rigorously test and refine all our designs in our very own test chamber we like to call AirLab. In fact, we also do engineering QA for other HVAC companies up and down the west coast. Why did we build this? Because this is what you need to build the most powerful, efficient and quiet whole house fan systems. It’s a huge competitive advantage. Plus, what’s more fun for an HVAC engineer than a day at the test chamber?


AirLab meets the HVI 916 standard required by the California Energy Commission and other authorities for air testing chambers.
